Abstract (en)

[origin: EP2067794A1] Use of a Ziegler-Natta procatalyst which contains a trans-esterification product of a lower alcohol and a phthalic ester for the production of reactor grade thermoplastic polyolefins with improved paintability, characterized in that the procatalyst used has been prepared by a) reacting a spray crystallized or emulsion solidified adduct of MgCl 2 and a C 1 -C 2 alcohol with TiCl 4 b) reacting the product of stage a) with a dialkylphthalate of formula (I) wherein R 1 ' and R 2 ' are independently at least a C 5 alkyl under conditions where a transesterification between said C 1 to C 2 alcohol and said dialkylphthalate of formula (I) takes place to form the internal donor c) washing the product of stage b) or d) optionally reacting the product of step c) with TiCl 4 ., as well as reactor grade thermoplastic polyolefins prepared by using the above described Ziegler-Natta procatalyst, use of these reactor grade thermoplastic polyolefins, molded articles produced from them and a method to improve paintability and/or surface quality of reactor grade thermoplastic polyolefin resin articles.
